lrparsing is a more recent entry in the LR parsing stakes:
https://pypi.python.org/pypi/lrparsing (although, as Russell put it in his
PyCon AU lightning talk, if PLY had shown up ranked higher than 506 in his
PyPI search for "parser", he probably would have just used that:
http://pyvideo.org/video/2222/sunday-lightning-talks at about 2:15)

(I plan to bug Russell about putting that up on one of the DVCS hosting
sites next time I see him at BrisPy - for the moment, the source is
available through the tarball/sdist)

Cheers,
Nick.
